Endoscopic Surgery for Frontal Sinusitis and Its Complications

Abstract
Endoscopic surgery of the paranasal sinuses has become popular during recent years, but the endonasal approach into the frontal sinus was only rarely recommended. Using a surgical endoscope with 70° optical deflection, the fenestration of the frontal sinus from below has proved a valuable and safe procedure in more than 500 procedures. The control of complications like osteitis and mucopyoceles, and of foreign bodies and benign tumors has become practical with endoscopic exposure.
